Defined in:

Overview

HTTP client for common observability endpoints exposed by the system under test.

This client is returned by observability and builds endpoint paths from Configuration#name.

Endpoints:

  • /<name>/healthz
  • /<name>/livez
  • /<name>/readyz
  • /<name>/metrics

Requests are performed using HTTPClient, so callers may pass RestClient options such as headers, open_timeout, and read_timeout.

Examples:

Nonnative.configure do |config|
  config.name = 'my-service'
  config.url = 'http://127.0.0.1:8080'
end

response = Nonnative.observability.health(read_timeout: 2, open_timeout: 2)
response.code # => 200
